HENRY B. WILLIAMS, OF FREMONT CENTRE, MICHIGAN, ASSIGNOR OF ONE- HALF TO JOSEPH GERBER, ()F SAME PLACE.

PIPE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 275,106,1iated April 3, 1883.

- Application filed February 8. 1883. (No model.)

To all whom it may concern Be it known that I, HENRY l3. WILLIAMS, of Fremont Gentre,in the county of Newaygo and State of Michigan, have invented new and useful Improvements in Pipe-Wrenches; and Ihereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, which form a part of this specification.

IO This invention relates to certain new and useful improvements in the construction of pipe-wrenches; and the invention consists in the peculiar construction, arrangement, and combination of the parts, as more fully herein- 1 5 after described and claimed.

Figure 1 is a side elevation of my improved pipe-wrench. Fig. 2 is a similar view of the stationary jaw. Fig. 3 is a longitudinal section of the adjustablejaw.

In the accompanying drawings, A represents the stationary jaw, which is provided with the tang B and the handle 0.

D represents the adjustable jaw, substantially of the form shown, andis longitudinally slotted to embrace the tang of thejaw A. At

the heel of the jaw D the sides of such jaw are secured together by the girt E,which forms an integral part of the jaw, and which, when the jaws are placed together, engages with one of the notches F in the edge of the tang.

G is a bar-spring, one end of which is rigidly secured by the ferrule H of the handle, while the opposite end rests upon the girt in the heel of thejaw I) and retains it in its adjusted positions. 5

in practice thejaw D is opened, and the article to be turned is placed between thejaws. By then lifting the handle the'jaws are compelled to tightly grasp the pipe and turn the .same. For use upon larger pipe the jaw D is 40 placed in the notch near the head orjaw; but for smaller pipe thejaw I) is adjusted further back upon the tang,which will bring the two jaws nearer together.

What I claim as my invention is 5 A pipe-wrench consisting of tbejaws A D. tang B, having notches F, and spring, G, fixed upon the handle and operating on the girt E, constructed substantially as described.

- HENRY B. WILLIAMS.
